Notes

An unusual feature of this watch is the alarm which has to be set in the same way it was working on the Louis XIV "oignons": the blued steel hand is revolving together with the hour hand and the alarm is released at 12. That means that it has to be set according to the number of hours to pass before it rings and not at the alarm time as in most of modern watches.
